Paleo/Primal one-liners/comebacks.

"Don't you know how bad all that fat is for you?"
"No. Don't you know how bad all that sugar is for you?"

"'Carbs' is a fancy word for 'sugar'."

"I prefer 'green carbs'." (Fruit and veg.)

"But you need to eat every 3 hours! Otherwise you'll just crash and be hungry and tired and unproductive!"
"I'd rather wait until I FEEL hungry than pre-empt it."

"If you are what you eat, what would you rather be: an animal or a vegetable?"

"Humans can't hunt without guns!"
"OK, when I go to see some tribespeople, I'll tell them that."

"Why is it that all the studies linking fat to poor health didn't bother to tell the difference between artificial and natural diets?"

"Oh, a 'calorie is a calorie', is it? I'll just go tell my insulin to pack its bags then, as its job is clearly over and done."

(From mi fiance's experience at work.)
Co-worker: "I just can't stop eating these M&Ms!"
*everyone around agrees that, once the bag is open, you MUST finish it*
Fiance: Here, hand me one. *is given an M&M; places it on the table* Is it jumping into your mouth?
*silence*
Fiance: Then you CAN stop eating them. You can thank me later.

"I'm being 'good' with my diet today. Having a low-fat yoghurt and a cereal bar for breakfast!"
"Oh, I fancy being 'good' too. I'll be 'good' with my exercise by breaking a leg and 'good' with my sleep by staying up until 5."

"Semi-skimmed milk is NOT the 'best of both worlds'. It is about as processed as dairy gets."

"Fanta is NOT 'orange juice'. Chocolate milk is NOT 'healthy dairy'. Pasta with some 2000-ingredient cream sauce is NOT 'a balanced meal'."

"How is 70% sugar a 'balanced' diet?"

"Why is it that, without my 'filling grains', I stay fuller longer than you?"

Have any more to share?

Perfection is entirely individual. Any philosophy or pursuit that encourages individuality has merit in that it frees people. Any that encourages shackles only has merit in that it shows you how wrong and desperate the human mind can get in its pursuit of truth.

I get blunter and more narcissistic by the day.
I'd apologize, but...

Another:
"It's such a shame I can't eat grains anymore, because now I'm having to eat more bacon, chicken, yoghurt, nuts, bananas... Such torment!"

"grains are not a food group, they are a handful of ingredients."
or
"tell me one nutrient I'm not getting by eliminating grains"
or
"Its not ok for me to cut out a couple of ingredients and get my nutrition from optimal sources, yet its acceptable for vegetarians to cut out meat and then stuff themselves with mediocre protein beans and tofurkey"

"Ah, those endless forests, and their horror-haunted gloom! For what eternities have I wandered through them, a timid, hunted creature, starting at the least sound, frightened of my own shadow, keyed-up, ever alert and vigilant, ready on the instant to dash away in mad flight for my life. For I was the prey of all manner of fierce life that dwelt in the forest, and it was in ecstasies of fear that I fled before the hunting monsters."
